To all whom it may concern.

Be it known that I, ARTHUR PRInoLE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Corner-Protectors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.- k

This invention relates to improvements in corner protectors.

One object of the invention is to provide a corner protector having an improved construction and arrangement of integral fastening devices whereby the protectors may be readily and firmly secured to the frame work without the use of additional fastening devices.

With this and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a cross sectional view of one form of my protector illustrating the application of the same to a frame work; Fig. 2 is a side View of the blank from which the same is formed; Fig. 3 is a similar view of another form of the invention; Fig. 4 is a cross sectional view of the same; Fig. 5 is aside view of another form of blank showing the invention; Fig. 6 is a detail sectional view of the same on the line 6-6 of Fig. 5; Fig. 7 is a cross sectional view of another form of the invention showing the same applied to a frame work; Fig. 8 is a side view of the blank from which the same is formed; Fig. 9 is a view similar to Fig. 7 showing a single form of protector provided with my im roved fastening devices; Fig. 10 is a si e view of the blank from which the same is formed; Fig. 11 is a cross sectional view of another form of the single protector; F ig. 12 is a side view of the blank from which the same is formed; Fig. 13 is a fragmentary perspective View of one form of the protector showing a modifled construction of'the fastening prongs; Fig. 14 is a cross sectional view of the prong on the line 14.l i of Fig. 13; Fig. 15 is a View similar to Fig. 13 showing another form of prong; Fig. 16 is a cross sectional view on the line l616 of Fig. 15.

Referring more particularly to Figs. 1 .toti of the drawings wherein is illustrated one form of the invention, 1 denotes the protector which in these figures is shown as being constructed in, double form from a singlestrip of sheet metal bent lengthwise midway between its ends to form a bead 2. The side members 3 of the protector are bent or curved outwardly toward their inner edges as shown. In the side members 3 near their outer ends are formed anchoring lugs 4 said lugs being preferably struck out of the metal forming the sides as shown, thereby providing means for anchoring the plaster to the corner protector.

The curved inner edges of the side members 3 are adapted to engage the opposite sides of the frame or structure to which the same are to be attached. In the side members of the protector are formed fastening lugs 5 which are also struck from or formed integral with the side members 3. The lugs 5 are tapered to sharp points and are bent outwardly from their inner ends at an angle. The points of the lugs are bent inwardly ata rightv angle to the main portion of the lugs and form fastening prongs 6 which are 'adapted to be driven into the frame work and thus firmly secure the protectors in place without the use of additional fastening devices.

The fastening lugs 5 are disposed at suitable intervals along the side members of the protectorand said lugs may be arrangedin the position shown inFigs. 1 and 2 wherein the lugs are struck out transverselyto the side members with their points projecting outwardly or with their points projecting inwardly as shown in Figs. 3 and 4. The lugs may alsobe arranged longitudinally of the side members of the protector as shown in Figs. 5 and 6. p

In Figs. 7 and 8 of the drawing the protector is shown as consisting of side meml bers or plates 7 arranged at, an angle and havin shortcurved outer edges which form.

0 ositel ro'ecting flanges 8 with which is ngage d a s eparate head 9. The bead 9 when engaged with the flanges serves to hold the outer edges of the plates or sides of the protectortoget-her and saldbead may be constructed of non-corrosive metal which will not rust and thus stain or show through the plaster. In the side plates near their outer edges are formed anchoring lugs 10 similar to the anchoring lugs 4 o the first form of the invention. The side lates 7 also into the frame work thus securely fastening this form of the protector in place. The lugs 11 which engage the sides of the frame between the lugs having the prongs serve to brace and hold the protector in position. In practice the lugs 12 of the protector are yielding and are formed in such a manner in respect to one another that the pointed ends thereof will grip the wooden frame work of the structure, whereby the protector may be readily positioned, after which the pointed ends are forced home during the completion of the structure.

In Figs. 9 and 10 is shown a single form of the protector in which only one plate 14 is employed. The plate 14 has formed at suitable intervals along its inner edge a series of V shaped lugs 15 which are alternately bent laterally in opposite directions at suitable angles and have their outer ends or points bent at right angles to form fastening prongs 16 which are driven into the wood and thus securely fasten the protector in place. The inneredge of the metal between the series of lugs 15 is bent laterally in opposite directions and at a suitable angle to engage the opposite sides of the frame, said edges thus forming bracing flanges 17 whereby the protector is centered and held in proper position. In this form the protector is rovided with anchoring lugs .18 constructed in the manner described.

In Figs. 11 and 12 is shown another single.

form of the protector in which the plate 19 has its inner edge out inwardly at intervals in a zig-zag line to form a series of lugs 20. In thus cutting the metal a series of V shaped points 21 are formed along the opposite edges of the lugs 20. The lugs 20 are alternately bent laterally in opposite directions and at a suitable angle to engage the opposite sides of the frame work and thus form braces. At intervals certain of the lugs 20 are bent outwardly above the sides of the frame and two or more of the points 21 on the side edges of these lugs are bent inwardly at right angles to formv fastening prongs 22 which are adapted to be driven into the wood and thus securely fasten the protectors in place. The last form of the protector is providedwith anchoring lugs 23 which are formed as hereinbefore described.

In Figs. 13 and 14 of the drawing is shown a modified form of prong 24 said rong being bent or folded upon itself longltudinally and centrally throughout its entire length, thereby increasing the strength and stiflness of the prong. In Figs. 15 and 16 is shown another form of prong 25 which is provided with a blunt or square end 26 and has its inner portion bent or folded on itself as shown at 27 thereby stiffening the prong. The prong as formed in Figs. 15 and 16 provides shoulders 28 which when driven into the wood or frame structure form a secure hold.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily-understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may ,be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim is:

1. A corner protector comprising a plate of metal, a bead formed on the outer edge thereof, a series of anchoring lugs formed therein near its outer edge, bracin flanges formed on its inner edges, fastening lugs struck from the plate, said lugs being bent atan angle at their outer ends to form fastening prongs adapted to be driven into the frame work of the structure to which the protectors are applied.

2. A corner protector comprising a metal plate, a series of fastening devices struck from the plate and bent outwardly and then inwardly at an angle to the outwardly bent portion to form fastening prongs adapted to be driven into the frame work to support the protector in operative position, said prongs having a folded longitudinally disposed portion whereby the same are stiffened.

3. A corner protector comprising a metal plate, a series of fastening devices struck from the plate and bent outwardly and then inwardly at an angle to form fastening prongs edapted to be driven into the fra ne In testimony whereof I have hereunto set workto support the protector in operative my hand in presence of two subscribing position, said prongs having a square or witnesses.
